Downpipe and sports cat - buying & fitting
JMP:
I think this is the same dp I have been running for a couple of years. I have mot'ted it twice and it passed emissions both times. But it was close, I did heat it up very well before to make sure it passes.
Installation is very simple. You might want to soak up the turbo nuts before installation. I had no problems with them and applied copper grease etc when installing. There was a bit tension with the mount to the frame but it has held up well. Its mated to my stock catback and really opens up the engine. Good increase in power and fuel consumption goes down.
For the money I think this is by far the best mod for my k03 mkv GTI.

re MOT that's the experience I've had with a similar cat & DP for my S3 8L, the bonus being it spooled up a lot quicker and the mpg improved by 2-4 mpg.
The one for my mk5 is waiting for me to put it on...
Spankiee:
Got my sports cat fitted the other day. Seems well made and fits good. But I literally drove it 15 minutes to the garage to get the wings replaced so not had chance to let it bed in yet. Mates upto my standard cat back no problems. Until I get my BCS ordered to really liven things up.
It certainly felt different to drive. And sounds a bit fruitier.

Did you fit it yourself ? Did you have difficulty with accessing the nuts ? Any gotchas ? Any tips ? How much of the car did you have to dismantle ? Does the subframe need to be dropped etc ?
Rob.:
I fitted my DP on axle stands on my drive. It was doable, but not a lot of fun! Trying to reach the flange studs and be able to put enough force into them, while lying on your back!
I put PlusGas on anything I could reach, didn't drop the subframe or anything like that. Unplugged a couple of sensors, removed a bit of beat shield. Followed a guide I found online (might have been Briskoda?)
